Sunday nights are never very fun for my wife and me. We've named it the Sunday Night Blues. You can't really start on any project because you'll have to put off the end when the week hits. Everything you do just feels like biding time before the week starts. You should be going to sleep, but you're not sleepy because you slept in or took a lazy Sunday nap. But every minute you stay awake is another unit of grogginess you'll have to deal with the next day. (By the way, what is the unit for grogginess? I propose the drooplid. You are 1 drooplid groggy if you do that head-jerking drift-into-dream-for-3-seconds thing we're all familiar with. If you're still mostly able to function, but you're still kind of tired, you're probably around 60 centidrooplids groggy. If you really can't keep your eyes open, you're probably 2 or 3 drooplids groggy. Any takers on that unit? Other suggestions?) So all you can do is watch lame TV or cruise the internet or play a game and think about work. That's the Sunday Night Blues.
My school starts up again in four days. Sure, I'm ready. Day One will probably go fine. I'm eager to meet my classes, and the constant daycare I'm providing to my daughter (while wonderful for bonding) is getting tiresome. There's only so much intellectual interest you can get from an 18-month-old. But...I can't start any big projects, etc., etc. It's Exponential Sunday Night Blues. And since the baby woke up before I wanted to, I have the Blues and I'm 75 centidrooplids groggy. Good thing this kid is so darned cute.
UPDATE: I realized that I need to calibrate my scale of drooplids. You know what 1 drooplid is, but we need a reference for 0 drooplids. 0 drooplids is the amount of grogginess after the following series of events: you got 8 hours of sleep on Saturday night, and you're at home alone all day on Sunday, and you take a nap at 12:30pm without setting an alarm, and wake up briefly at 1:30, but you still feel a little tired so you drift back to sleep until 2:45, when you wake up on your own and you realize you still have half a free day with nothing to do but read and work out and watch a movie. I don't expect that to happen to me again before I retire, but that's 0 drooplids. Insomnia due to caffeine is measured in negative drooplids.
